Projecting global GHG emissions methods to estimate future global GHG emissions or removals by sinks

Inventorying greenhouse gas (GHG) emissions methods to estimate GHG emissions from sources or sequestration by sinks

A. Inventorying GHG emissions and sinks

Trends in CO2 emissions from transport, total CO2 emissions and total GHG emissions

B. Projections of GHG emissions and sinks

Therefore GHG emissions from this subsector will grow.

Projecting national GHG emissions methods to estimate future GHG emissions or removals by sinks, for example, extrapolation, expert judgement, linear programmes and macroeconomic models

The trend in total GHG emissions varied among Parties.

For all Parties except one, the largest share of total GHG emissions was CO2, accounting for 83 per cent of total 1995 GHG emissions of the Parties.

Therefore GHG emissions can be expected to increase from this subsector.

Italy, however, has avoided establishing its own national target regarding GHG emissions.

Romania has no voluntary quantified target for the reduction of GHG emissions.

GHG emissions in 1994 were 20 per cent lower than in 1990.

As these emissions are considered as part of the GHG emissions of the session they may be offset twice.

Removals by LUCF in most Parties offset GHG emissions from this same sector.

The national communication contains projected estimates of GHG emissions for the year 2000.

Total GHG emissions increased from 1990 to 1995 for about half of the Parties, and for all reporting Parties combined total GHG emissions increased from 1990 to 1995 by about 1.7 per cent.

The largest source of total GHG emissions and of CO2 emissions was fuel combustion (83 and 97 per cent respectively).

Some stressed the need to develop a comprehensive energy balance to help compute GHG emissions in the energy sector on a continuous basis, and a few pointed out the need to link the energy balance with GHG emissions methodologies such that data changes in the energy balance are automatically reflected in the GHG emissions values.

Sequestration of carbon dioxide (CO2) emissions by the LUCF sector in most Parties offset the GHG emissions originating from this sector.

For all the Parties reporting emissions of HFCs, the increase in emissions in percentage was greater than for any other GHG.

They believe that these measures will result in reduction of growth of GHG emissions.

Top down and bottom up methods are used to estimate GHG emissions from air travel.

The SBI noted that such documents should also include additional information on net' GHG emissions.

Moreover, as Italy has no well defined national GHG emissions target, stabilization of emissions by 2000 is not perceived as a national goal.

For 83 per cent of the total 1990 GHG emissions the highest confidence level was reported.

Descriptions include the potential up and down sides of market restructuring in relation to GHG emissions.

In that case, the future GHG emissions reductions were computed with an quot average scenario quot .

The total GHG emissions in 1995 for the 18 Parties considered in this document represent only about 60 per cent of the total GHG emissions for the 31 Parties considered in the second compilation and synthesis report on first national communications.

Estimation of emission reduction Some Parties included an assessment of the impacts of measures on GHG emissions.

Although the share of these emissions in total N2O emissions is only 15 per cent, and less than 1 per cent of total GHG emissions, these emissions have grown substantially, more than 35 per cent, since 1990.

It does not envisage using increased taxation at the local level as an instrument for reducing GHG emissions.

Methane held the second largest share (11 per cent) of GHG emissions, followed by N2O (4 per cent).

Many of these partnership arrangements are with industry and aim to reduce GHG emissions per unit of production.

For all Parties reporting emissions of HFCs, the increase in percentage was greater than for any other GHG.

Many of these partnership arrangements are with industry and aim to reduce GHG emissions per unit of production.

The effects of policies and measures on other GHG emissions were reported by three Parties (DEU, GBR, USA).

Instead, the land use change and forestry sector is the biggest source of emissions (more than half of total GHG emissions in 1994), mainly due to desertification.

The largest number of measures and those that are projected to make the largest contribution to reducing total GHG emissions in 2000 and beyond still target CO2 emissions.

Categories of sources of GHG emissions or their sinks corresponding to the IPCC guidelines nomenclature are given in italics.

For COP 10, Parties and observer States accounted for only 43 per cent of the GHG emissions from travel observer organizations accounted for more than 46 per cent of the GHG emissions from travel (41 per cent by NGOs) and media accounted for 5.3 per cent.

Total GHG emissions of these 18 Parties taken together increased from 1990 to 1995 by about 1.7 per cent, although the trend in total GHGs emissions varied amongst Parties.

A majority of Parties include energy market restructuring as an important policy which has implications for GHG emissions, though emissions reduction is not the primary purpose of the reforms.
