In a special report, the IEA analysed more than 400 clean energy technologies and said that although renewable technologies in use now can deliver a large amount of emissions reductions, they are not enough on their own.It found that there are currently few technologies available for reducing emissions to zero in sectors such as shipping, trucking, aviation and heavy industries.

Climate mitigation measures could impact food security, study finds

Many countries have set carbon neutrality as a policy goal, but according to a new study by an international team of researchers from IIASA, Japan, and the US, there are various risks associated with the reduction of greenhouse gases, especially in the agriculture, forestry, and land use sectors, that need to be considered when formulating mitigation strategies. While eliminating emissions from the energy sector is undoubtedly a step in the right direction to reach the goals of the Paris Agreement, agriculture, forestry, and other land use accounted for 20-25% of global greenhouse gas emissions in 2010. According to the authors of the study just published in Nature Food, both the magnitude of baseline emissions and the impact on other Sustainable Development Goals when trying to mitigate these emissions, means that this sector cannot be ignored in the context of meeting ambitious long-term climate change mitigation targets. The strategies needed to decarbonize the agriculture, forestry, and other land use sectors, however, may cause food prices to soar, which may have a potential negative impact on food security. The authors suggest three main reasons for this. The first of these is increased costs associated with methane and nitrous oxide abatement. Secondly, current decarbonization strategies could cause intensified competition for land due to the expansion of bioenergy crops; and lastly, they could lead to a higher value being placed on forest carbon to sequester additional carbon and prevent large-scale plantations and bioenergy crops from encroaching on forestland. Although these factors are thought to affect agricultural markets through different mechanisms, it is still uncertain to what extent they could affect future agricultural prices and food security.
