Welcome to the EU-27 GHG emissions and reduction targets summary.

This tool presents compilation of the historical EU-27 GHG emissions and allows for the exploration of 2050 reduction targets for anthropogenic GHG emissions leading to the levels of future warming between 2 °C and 4+ °C.

EU-27 GHG emissions and reduction targets

Additional description

Historical anthropogenic emissions

We present estimates of the anthropogenic GHG emissions divided into two categories: (1) the technospheric emissions, consisting mainly of the CO2 emissions from fossil-fuels burning; and (2) the emissions resulting from the land use, land-use change and forestry (LULUCF) activities. For each category we give the activity-based estimates of emissions as well as the consumption-based emissions estimates which take into account the emissions transfers due to international trade (i.e. emissions embodied in the production and transport of goods consumed on the Austrian territory).

Reduction target paths

We present the linear target paths for reductions of technospheric GHG emissions compatible with the global warming stabilization levels of 2°C, 3°C, 3°C-4°C and ≥4°C (corresponding to EU-27 share of) 2000-2050 cumulative global GHG emissions budgets of 1500 Gt CO2-eq, 1800 Gt CO2-eq, 2100 Gt CO2-eq and 2400 Gt CO2-eq, respectively). For each warming level the target paths for reductions starting in 1990, 2000 and 2010 are provided. These target paths should be used as a reference. Each warming level can be achieved by any scenario as long as both (i) the area under the scenario’s emissions path (i.e. cumulative emissions) and (ii) the 2050 emissions target are the same as for the corresponding reference linear target path.

When calculating reduction paths for the technospheric GHG emissions we assume that: (1) by 2050 the sustainable land use (in terms of zero net emissions) will be achieved (see the ’2050 LULUCF sust,’ target path); and (2) remainder of the unmanaged biosphere stays in or returns to the zero net emissions balance.

International reductions obligations

We present the EU-27 obligations for GHG emissions reductions: (i) declared in the Kyoto protocol (EU's Burden Sharing Mechanism), (ii) declared for the post-Kyoto period (optimistic and pessimistic pledges) and (iii) stated in the EU's Effort Sharing Mechanisms (implementing EU's 20-20-20 targets).

Projections of future emissions

We present the projections of future EU-27 CO2 emissions related to the energy production, published by the International Energy Agency (IEA) for the three representative scenarios corresponding to the 2 °C, 4 °C and 6 °C warming levels.

Projections of future emissions

We present the projections of future global CO2 emissions related to the energy production, published by the International Energy Agency (IEA) for the three representative scenarios corresponding to the 2 °C, 4 °C and 6 °C warming levels.

We present projections of future GHG emissions under three exemplary long-term scenarios of ambitious mitigation efforts generated by energy-climate models: GTEM, POLES and IMAGE. GTEM is an inter-temporal computable general equilibrium model that emphasizes the link between mitigation action and the economy and its different sectors; POLES is a simulation model with high technology resolution in the energy system; and IMAGE is an integrated assessment model with an elaborate land-use module. Although these models follow different methodological approaches, all three presented scenarios lead to warming level between 2 °C and 3 °C.
