چکیده
Abstract. To track progress towards keeping warming well below 2 °C, as agreed upon in the Paris Agreement, comprehensive and reliable information on anthropogenic sources of greenhouse gas emissions (GHG) is required. Here we provide a dataset GHG 1970–2019 with broad country sector coverage. We build from recent releases “Emissions Database for Global Atmospheric Research” (EDGAR) CO2 fossil fuel combustion industry (FFI), CH4 emissions, N2O fluorinated gases, use well-established fast-track method to extend this 2018 2019. complement data net land use, land-use change forestry (LULUCF) three bookkeeping models. an assessment uncertainties each at 90 % confidence interval (5th–95th percentile) by combining statistical analysis comparisons global inventories expert judgement informed relevant scientific literature. identify important gaps: could be respectively 10–20 % higher than reported EDGAR once all are accounted. F-gas estimates individual species EDGARv5 do not align atmospheric measurements total exceeds measured concentrations about 30 %. However, official national emission reports under UNFCCC comprehensively cover species. Excluded such chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) larger sum 2019 amounted 59 ± 6.6 GtCO2eq: FFI were 38 ± 3.0 Gt, LULUCF 6.6 ± 4.6 Gt, 11 ± 3.3 GtCO2eq, 2.4 ±1.5 GtCO2eq F-gases 1.6 ± 0.49 GtCO2eq. Our global, trends over past five decades (1970–2019) highlights pattern varied, but sustained growth. There high that have increased every decade. Emission growth has been persistent across different (groups of) gases. While accounted almost 75 % since 1970 terms CO2eq here, combined grown faster rate other GHGs, albeit starting low levels 1970. Today, make non-negligible contribution – even though CFCs HCFCs, regulated Montreal Protocol included our estimates, contributed more. further 2010-2019 any previous decade most average annual slowed between 2010–2019 compared 2000–2009, absolute increase decadal 2000s 2010s largest 1970s within human history suggested available long-term data. note considerably rates entire 2010–2019, which numerically comparable period during 2000s, place finding majority driven highly uncertain increases CO2-LULUCF preliminary extrapolation methodologies these years. there growing number countries today reduction trajectory, reveals no sectors show reductions emissions. conclude highlighting tracking climate policy requires substantial investments independent accounting monitoring international infrastructures.

Human drivers of national greenhouse-gas emissions
Centuries of speculation about the causes of human stress on the environment is now being disciplined with empirical evidence, including analyses of differences in greenhouse-gas emissions across contemporary nation states. The cumulative results can provide useful guidance for both climate projections and for policy design. Growing human population and affluence clearly contribute to enhanced ...
متن کاملReducing greenhouse gas emissions for climate stabilization: framing regional options.
The Intergovernmental Panel on Climate Change (IPCC) has stated that stabilizing atmospheric CO2 concentrations will require reduction of global greenhouse gas (GHG) emissions by as much as 80% by 2050. Subnational efforts to cut emissions will inform policy development nationally and globally. We projected GHG mitigation strategies for Minnesota, which has adopted a strategic goal of 80% emiss...
متن کاملHuman nitrogen fixation and greenhouse gas emissions: a global assessment
The net impact of human nitrogen (N) fixation on climate (ignoring short-lived components) mainly depends on the magnitude of the warming effect of (direct and indirect) nitrous oxide (N2O) emissions and the cooling effect of N-induced carbon dioxide (CO2) uptake. N-induced CO2 uptake is caused by anthropogenic N deposition which increases net primary production (NPP) in N-limited ecosystems an...
متن کاملTracing Greenhouse Gas Emissions in Global Value Chains
This paper integrates two lines of research into a unified conceptual framework: trade in global value chains and embodied emissions. This allows both value added and emissions to be systematically traced at the country, sector, and bilateral levels through various routes in global production networks. By combining value-added and emissions accounting in a consistent way, the potential environm...
