Convention on Certain Conventional Weapons (CCW or CCWC), concluded at Geneva on October 10, 1980, and entered into force in December 1983, seeks to prohibit or restrict the use of certain conventional weapons which are considered excessively injurious or whose effects are indiscriminate. The full title is Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons Which May Be Deemed to Be Excessively Injurious or to Have Indiscriminate Effects. The convention covers

Objectives

The aim of the Convention and its Protocols is to provide new rules for the protection of
civilians Civilians under international humanitarian law are "persons who are not members of the armed forces" and they are not "combatants if they carry arms openly and respect the laws and customs of war". It is slightly different from a non-combatant, b ...

(CWC) serves as an umbrella for protocols dealing with specific weapons. The Convention and its annexed Protocols apply in all types of armed conflict, both international and non-international. This was not the case when the convention was first adopted, but the scope was expanded by two conferences in 1996 and 2001. Some provisions also apply after open hostilities has ended, such as the rules in protocols II and V about minimizing the dangers from mines and other ordnance. CCWC lacks verification and enforcement mechanisms and spells out no formal process for resolving compliance concerns. A state-party can refute its commitment to the convention or any of the protocols, but it will remain legally bound until one year after notifying the treaty depositary, the UN Secretary-General, of its intent to be free of its obligations.


Adoption and entry into force

The CCWC consist of a set of ''additional protocols'' first formulated on October 10, 1980, in Geneva and entered into force on December 2, 1983. As of the end of October 2020, there are 125 state parties to the convention. Some of those countries have only adopted some of the five protocols, with two being the minimum required to be considered a party. The convention has five protocols: *Protocol I restricts weapons with non-detectable fragments *Protocol II restricts landmines, booby traps *Protocol III restricts incendiary weapons *Protocol IV restricts blinding

s (adopted on October 13, 1995, in Vienna) *Protocol V sets out obligations and best practice for the clearance of explosive remnants of war, adopted on November 28, 2003, in Geneva Protocol II was amended in 1996 (extending its scope of application), and entered in force on December 3, 1998. The amendment extended the restrictions on landmine use to internal conflicts; established reliability standards for remotely delivered mines; and prohibited the use of non-detectable fragments in anti-personnel landmines (APL). The failure to agree to a total ban on landmines led to the Ottawa Treaty.


Protocol I: Non-Detectable Fragments

Protocol I on Non-Detectable Fragments prohibits the use of any weapon the primary effect of which is to injure by fragments which are not detectable in the human body by X-rays. The reason is that such fragments are difficult to remove and cause unnecessary suffering. The protocol applies when the "primary effect" is to injure by non-detectable fragments and does not prohibit all use of e.g. plastic in weapons design.


Protocol II: Mines, Booby Traps and Other Devices

Protocol II on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices was amended on May 3, 1996, to strengthen its provisions and extend the scope of application to cover both international and internal

Protocol III: Incendiary Weapons

Protocol III on Prohibitions or Restrictions on the Use of Incendiary Weapons prohibits, in all circumstances, making the civilian population as such, individual civilians or civilian objects, the object of attack by any weapon or munition which is primarily designed to set fire to objects or to cause burn injury to persons through the action of

Protocol IV: Blinding Laser Weapons

Protocol IV on Blinding Laser Weapons prohibits the use of laser weapons specifically designed to cause permanent
blindness Visual impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment� ...
. The parties to the protocol also agree to not transfer such weapons to any state or non-state entity. The protocol does not prohibit laser systems where blinding is an incidental or collateral effect, but parties that agree to it must take all feasible precautions to avoid such effects.


Protocol V: Explosive Remnants of War

Protocol V on Explosive Remnants of War requires the clearance of UXO (unexploded ordnance), such as unexploded bomblets from

s to assist with the clearance of unexploded ordnance that this use has created. Parties are also required, subject to certain qualifications, to provide information on their use of explosive weapons. Each party is responsible for the territory in their control after a conflict. The protocol does not apply to mines and other weapons covered by protocol II. The protocol came about as a result of a growing awareness during the 1990s that the protection against unexploded ordnance was insufficient. The protocol was adopted in 2003 and entered into force in 2006.


Other proposals

As of 2017, the CCW has failed to achieve consensus to open negotiations on adding a compliance mechanism to help ensure parties honor their commitments, as well as negotiations on banning oversized-caliber bullets (5.56 or smaller). China and Russia have opposed restrictions on anti-vehicle mines, such as a requirement that such mines self-deactivate. In the 2010s the CCW opened talks on restricting
