Greenhouse gas emissions from air transport, and methods to calculate them, are notwell defined in the current literature. While calculating the direct emissions of CO2 is already causefor some debate, the contribution of other emissions and impacts – like nitrogen oxides (NOx),contrails, water vapour – to climate change still lacks a reliable metric. As aviation is the largestemitter of greenhouse gases within tourism, accurate estimates of carbon and non-carbon emissions are important. This paper presents some standardisation as well as general insights to assistresearchers assessing the impact of aviation on climate change in scenario studies or evaluatingmitigation policies. The IPCC introduced a radiative forcing index (RFI) to measure the role of aviation in climate change, which is in scenario studies or evaluations of policies often used as a kind ofconstant ‘equivalence factor’. The paper shows this to be inaccurate and proposes ways to accountfor both carbon and non-carbon climate impacts of air transport

Energiebeheer gericht aanpakken, Het analyseren van doelstellingen, resultaten en impacts van energie- en broeikasgasbeheersprogramma’s in bedrijven (met een samenvatting in het Nederlands): De wereldwijde uitstoot van broeikasgassen moet drastisch worden teruggebracht om de mondiale stijging van de temperatuur tot het relatief veilige niveau van maximaal 2 graden Celsius te beperken. In de komende decennia zal de verbetering van de energie-efficiëntie de belangrijkste strategie zijn voor het verminderen van de energiegerelateerde uitstoot van broeikasgassen. Hoewel er een enorm potentieel is voor verbetering van de energie-efficiëntie, wordt een groot deel daarvan nog niet benut. Dit wordt veroorzaakt door diverse investeringsbarrières die de invoering van maatregelen voor energie-efficiëntie verbetering verhinderen. De invoering van energiemanagement wordt vaak beschouwd als een manier om dergelijke barrières voor energiebesparing te overwinnen. De invoering van energiemanagement in bedrijven kan worden gestimuleerd door de introductie van programma's voor energie-efficiëntie verbetering en vermindering van de uitstoot van broeikasgassen. Deze programma's zijn vaak een combinatie van verschillende elementen zoals verplichtingen voor energiemanagement; (ambitieuze) doelstellingen voor energiebesparing of beperking van de uitstoot van broeikasgassen; de beschikbaarheid van regelingen voor stimulering, ondersteuning en naleving; en andere verplichtingen, zoals openbare rapportages, certificering en verificatie. Tot nu toe is er echter beperkt inzicht in het proces van het formuleren van ambitieuze doelstellingen voor energie-efficiëntie verbetering of het terugdringen van de uitstoot van broeikasgassen binnen deze programma's, in de gevolgen van de invoering van dergelijke programma's op de verbetering van het energiemanagement, en in de impact van deze programma's op energiebesparing of de vermindering van de uitstoot van broeikasgassen. De centrale onderzoeksvraag van dit proefschrift is als volgt geformuleerd: "Wat is de impact van energie- en broeikasgasmanagement programma’s op het verbeteren van het energiemanagement in de praktijk, het versnellen van de energieefficiëntie verbetering en het beperken van de uitstoot van broeikasgassen in bedrijven?".

Food production and consumption have a range of sustainability implications, including their contribution to global emissions of greenhouse gases (GHGs). As some foodstuffs entail higher GHG emissions than others, managing their use in tourism-related contexts could make a significant contribution to climate change mitigation. This article reviews the carbon intensity of selected foods and discusses how foodservice providers could adapt their practices. It shows that even though food management could substantially reduce the GHG emissions of foodservice providers, its application is currently hampered by the complexity of food production chains and a lack of dependable data on the GHG intensity of foodstuffs. Nevertheless, it is possible to make a number of recommendations in respect of how foodservice providers can better purchase, prepare and present foods. Further research is now needed to refine and extend our understanding of the contribution that food management can make to reducing tourism's carbon 'foodprint'.

In the Glasgow declaration (2021), the tourism sector promised to reduce its CO2 emissions by 50% and reduce them to zero by 2050. The urgency is felt in the sector, and small steps are made at company level, but there is a lack of insight and overview of effective measures at global level.This study focuses on the development of a necessary mix of actions and interventions that the tourism sector can undertake to achieve the goal of a 50% reduction in greenhouse gases by 2030 towards zero emissions by 2050. The study contributes to a better understanding of the paths that the tourism sector can take to achieve this and their implications for the sector. The aim of the report is to spark discussion, ideas and, above all, action.The study provides a tool that positively engages the sector in the near and more distant future, inspires discussion, generates ideas, and drives action. In addition, there will be a guide that shows the big picture and where the responsibilities lie for the reduction targets. Finally, the researchers come up with recommendations for policymakers, companies, and lobbyists at an international and European level.In part 1 of the study, desk research is used to lay the foundation for the study. Here, the contribution of tourism to global greenhouse gas emissions is mapped out, as well as the image and reputation of the sector on climate change. In addition, this section describes which initiatives in terms of, among other things, coalitions and declarations have already been taken on a global scale to form a united front against climate change.In part 2, 40 policies and measures to reduce greenhouse gas emissions in the sector are evaluated in a simulation. For this simulation, the GTTMdyn simulation model, developed by Paul Peeters from BUAS, is used which works on a global scale and shows the effect of measures on emissions, tourism, transport, economy, and behaviour. In this simulation, the researchers can 'test' measures and learn from mistakes. In the end one or more scenarios will; be developed that reach the goals of 50% reduction in 2030 and zero emissions in 2050. In part 3, the various actions that should lead to the reduction targets are tested against the impacts on the consequences for the global tourism economy, its role in providing leisure and business opportunities and the consequences for certain destinations and groups of industry stakeholders. This part will be concluded with two workshops with industry experts to reflect on the results of the simulation.Part 4 reports the results of the study including an outline of the consequences of possibly not achieving the goal. With this, the researchers want to send a warning signal to stakeholders who may be resistant to participating in the transition.
Client: Blue Plan regional activity centre (UNEP/MAP), subcontracted through TEC Conseille, Marseille As part of a regional workshop organized by the Blue Plan in July 2008, one of the conclusions of the Group "Tourism and Climate Change” was the need for saving energy in tourism transportation and particularly of air transport, as air transport is responsible for the largest share of greenhouse gas emissions caused by tourism. In the period 1998-2005, the share of international arrivals by air in the Mediterranean area rose from 23% to 40%, respectively, or in numbers, from 47 to 122 million tourists. Some countries, particularly islands, almost entirely depend on air transport for their international tourism. For example in 2005 air transport is used by 87%, 78%, 73%, 64% and 51% of international tourists arriving in, respectively, Israel, Egypt, Spain, Tunisia and Morocco. According to Plan Bleu forecasts on international arrivals, assuming that the share of air transport remains the same, the number of tourists travelling by plane will reach over 158 million by 2025. Given the role of aviation in the emissions of greenhouse gases (GHG), such a development is clearly not sustainable in the light of the necessary reduction of emissions to avoid dangerous climate change. The overall aim of the study is to inform policy makers and entrepreneurs in both destination and in origin countries, on possible options to reduce emissions of greenhouse gases from air travel, while at the same time not impairing the economic development of tourism. To do this, CSTT has developed a tourism scenario model for all countries with Mediterranean coasts describing inbound and outbound international tourism and domestic tourism by all available transport modes and giving both contributions to GDP and total GHG emissions. This model responses to global mitigation policies (increasing the cost of carbon emissions) as well as national policies (taxes, subsidies and changes in transport quality per transport mode). Using the model both global and national policies can be assessed as well as the risks of global mitigation policies for specific countries.
Indonesia’s peat forests remain severely threatened by forest fires, oil palm plantation development and extractive industries, which leads to biodiversity loss, increased emissions of greenhouse gases, and the marginalization of Indigenous Peoples and local communities. In 2008 the Government of Indonesia introduced the Social Forestry Programme under which Indigenous Peoples and local communities can acquire a 35-year management permit. Since then, about 10 percent of Indonesian State Forest has been designated for community-based forest conservation and restoration initiatives. The devolution of authority to the local level has created a new playing field. The Social Forestry Programme reverses more than a century of centralistic forest policy, and requires a fundamental re-orientation of all actors working in the forestry sector. The central question underlying this proposal is how Dutch civil society organizations (applied universities and NGOs) can effectively support Indigenous Peoples and local communities in the protection and restoration of peat forests in Indonesia. This project aims to set up a Living Lab in Ketapang District in West Kalimantan to study, identify and test novel ways to work together with a variety of stakeholders to effectively conserve and restore peat forest. In Ketapang District, Tropenbos Indonesia has assisted three Village Forest Management Groups (Pematang Gadung, Sungai Pelang and Sungai Besar) in securing a Social Forestry Permit. Students from three Dutch Universities (Van Hall Larenstein, Aeres Hogeschool and Inholland) will conduct research in partnership with students from Universitas Tanjungpura on the integration of local ecological knowledge and technical expertise, on the economic feasibility of community-based forestry enterprises, and on new polycentric governance structures. The results of these studies will be disseminated to policy makers and civil society groups working in Indonesia, using the extensive networks of IUCN NL and Tropenbos Indonesia.
